WHAT IT DOES

What create_sdn_subnet does on Proxmox MCP Server

AI agents use create_sdn_subnet to create or update resources in Proxmox MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Proxmox MCP Server environment.

RISK

Why create_sdn_subnet is rated Medium

This tool creates new SDN (Software Defined Networking) subnet resources within Proxmox infrastructure. While creating network infrastructure is a write operation that modifies system state and could have broad impact on network topology and connectivity across virtual machines and containers, it does not irreversibly destroy data or infrastructure.

From the tool's definition Tool name 'create_sdn_subnet' and description 'Create a subnet for an SDN VNet' indicate creation of network infrastructure configuration. The action is reversible (subnets can be deleted), not irreversible deletion.

RECOMMENDED RULE

The rule that runs create_sdn_subnet safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Proxmox MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_sdn_subnet, this is the rule to start with:

create_sdn_subnet Rate-limited

create_sdn_subnet stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Proxmox MCP Server, apply this rule, and every create_sdn_subnet call is checked against it from then on.

FAQ

Questions about create_sdn_subnet

What does the create_sdn_subnet tool do? +

Create a subnet for an SDN VNet. It is categorised as a Write tool in the Proxmox MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_sdn_subnet? +

Register the Proxmox MCP Server MCP server in PolicyLayer and add a rule for create_sdn_subnet: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Proxmox MCP Server. Nothing to install.

What risk level is create_sdn_subnet? +

create_sdn_subnet is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_sdn_subnet? +

Yes. Add a rate_limit block to the create_sdn_subnet rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block create_sdn_subnet completely? +

Set action: deny in the PolicyLayer policy for create_sdn_subnet. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides create_sdn_subnet? +

create_sdn_subnet is provided by the Proxmox MCP Server MCP server (gethosthewalrus/proxmox-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
